Recovery efforts ramp up for Qld floods

Flood-ravaged north Queensland communities will have the direct attention of the state government in coming days as two ministers and a recovery chief head to the region to help get them back on their feet.

Premier Annastacia Palaszczuk has appointed a state recovery coordinator and will send two members of her cabinet to the disaster zone to ensure the clean up runs smoothly.

Major damage to roads, bridges and other vital infrastructure is expected to emerge over coming days as floodwaters subside.

But Queensland's flood emergency might not be over.

Authorities are closely watching a low pressure system in the Coral Sea, which could develop into a cyclone later this week and deliver another drenching in some parts of the state.

"At this stage, it's expected the weather will be Mackay south. So those communities that have been impacted should not see the harshest impact from that weather from the Coral Sea," Ms Palaszczuk told reporters on Monday.

About a third of Queensland's local government areas have been affected by flooding.
